Description
Technical field
The present invention relates to a kind of method that is used to manufacture the acrylic resin of transfer printing functional membrane and prepares this acrylic resin.
Background technology
In order to prevent that commodity (as tobacco and wine, medicine etc.) from making moist, and make its packaging external appearance have aesthetic feeling, just need be on the ground of commodity packaging material compound thin film.Traditional method is compound one deck aluminium foil on the ground of paper wrapper, or aluminized plastics film is compounded on the ground of paper wrapper.Though adopt aforesaid method can reach protection against the tide and effect with aesthetic feeling.But the former need consume a large amount of aluminiums, and production cost is higher.And the latter is owing to contain plastics film, and the plastics film difficult degradation, can pollute environment.Therefore the wrapping material made from aforesaid method all are difficult to reclaim papermaking owing to contain one deck aluminium foil or plastics film.
Summary of the invention
The object of the present invention is to provide a kind of acrylic resin.Make the transfer printing functional membrane with this acrylic resin, be compound on the paper and the wrapping material of making again, low, the easy degraded of production cost, free from environmental pollution, easy recovery are used for papermaking.
Another object of the present invention provides a kind of method for preparing acrylic resin.
Above-mentioned purpose of the present invention is realized by following technical solution:
Acrylic resin of the present invention is made by the raw material of following parts by weight:
5～10 parts of the modified monomers of 15～30 parts of alkyl methacrylate monomers, band shape structure, 60～70 parts of organic solvents, 0.1～1.2 part of initiator.
Wherein: alkyl methacrylate monomer is any one in the methacrylic acid C1-C8 alkyl ester monomer; The modified monomer of band shape structure is any one in vinylbenzene, N-phenylmaleimide, cyclohexyl maleimide and the cyclohexyl methacrylate; Organic solvent is N-BUTYL ACETATE or pimelinketone; Initiator is any one in Diisopropyl azodicarboxylate, benzoyl peroxide and the tert-butyl peroxide.
The method for preparing the aforesaid propylene acid resin:
Earlier 1/3 organic solvent is poured in the reactor, and under 60～80 rev/mins rotating speed, stirred;
When continue stirring, alkyl methacrylate monomer is mixed with 1/3 initiator, make mix monomer;
When continue stirring, the solvent in the reactor is heated to 80～85 ℃, under this temperature, above-mentioned mix monomer is evenly splashed in the solvent in the reactor with 60～90 fens clock times, and constant temperature maintenance 100～140 minutes under 80～85 ℃ temperature;
Then, when continuing stirring, 1/3 organic solvent is poured in the reactor, and reactor is heated; When its temperature rose to 110～115 ℃, constant temperature kept 160～200 minutes;
Afterwards, the initiator with 1/3 mixes with 1/6 organic solvent, makes initiator solution; And slowly poured into this initiator solution in the reactor in the clock time at 50～70 minutes;
Afterwards, constant temperature kept 50～70 minutes under 110～115 ℃ temperature;
Afterwards, with behind 1/3 initiator of remainder and the band cyclic modified monomer uniform mixing, pour in the reactor;
Afterwards, reactor is heated; When its temperature rose to 120～125 ℃, constant temperature kept 25～35 minutes;
Again, 1/6 organic solvent of remainder to going in the reactor, is continued to stir 20～30 minutes;
Allow its naturally cooling then, when its temperature is reduced to 90～100 ℃, filter, obtain acrylic resin of the present invention.
Adopt such scheme, have the following advantages:
Adopt roller coating technology, acrylic resin roller coat of the present invention on the PET film, and through the drying tunnel baking, is formed the dry and comfortable film of one deck on the PET film.Then, on the dry and comfortable film of this layer, carry out vacuum aluminum-coatedly, plate the very thin aluminium film of one deck.Again with its adhesive transfer on paper, can print various exquisite patterns thereon, this has just made not only the paper wrapper that can be moistureproof but also has aesthetic feeling.
After making film with acrylic resin of the present invention, only need plate the very thin aluminium of one deck thereon by vacuum coating method, promptly alternative traditional aluminium foil, required aluminium is few, can reduce production costs greatly.
Again because the film made with acrylic resin of the present invention is easy degradation material, they and paper be combined with each other and the paper wrapper that makes, not only easily degraded, free from environmental pollution, use is afterwards also recyclable to be used for papermaking.
